What's the difference between a battery and a lithium battery?

The storage battery is one of the batteries. Its role is to be able to keep the electricity and be used in the right place. Its working principle is to convert chemical energy into electricity.

Fill it with sponge lead plate as cathode, fill the lead plate made of lead dioxide anode, with 22 ~ 28% of dilute sulphuric acid as electrolyte. When charging, electrical energy into chemical energy, discharge chemical energy into electricity. Battery during discharge, the metal lead is negative, the oxidation reaction, oxidized lead sulfate; Lead dioxide is positive, reduction reaction, reduction of lead sulfate. When used in dc rechargeable batteries, lead and lead dioxide generated poles respectively. Remove the power supply, it back to the front of the discharge state, form a chemical battery. Can lead battery is repeatedly charging and discharging of battery, is called the secondary battery. It is 2 v voltage, usually the three lead battery used together, the voltage is 6 v. Cars with six series lead battery into the 12 v battery pack. Lead battery in use after period of time to add sulfuric acid, keep the electrolyte contains 22 ~ 28% of dilute sulphuric acid.

The lithium battery is a kind of lithium metal or lithium alloy anode materials, the use of water electrolyte solution of the battery. The earliest of lithium battery from the great inventor Thomas Edison.

Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment. So, the lithium battery has not been applied for a long time.

With the development of microelectronics technology in the 20th century, increasing miniaturization of equipment, puts forward high demands on the power supply. Then entered the practical stage of large-scale lithium-ion batteries.

The earliest to use in cardiac pacemaker. Due to the lithium battery self-discharge rate is extremely low, flat discharge voltage. That makes it possible to pacemaker implantation in the human body use for a long time.

Lithium batteries tend to have higher than the nominal voltage of 3.0 v, is more suitable for integrated circuit power supply. Manganese dioxide battery, is widely used in computers, calculators, cameras, watches.
